My grandfather served in the Navy in WWI. Freedman's account of the brutality of trench warfare and the tremendous loss of life is chilling. Sure gives me a better picture of this time in history. Hard to image that 650 million men fought in this war and that over half of them sustained casualties of war: either death, injury, missing in action, prisoner of war, etc. Particularly interesting is the changes during this war in technologies used in warfare..... communication radios, tanks, airplanes, artillery, and the horrible chemicals used by both sides. For those who like to read about war history, this is a satisfying read. Then, when finished with the book, watch the movie "All Quiet on the Western Front."
